FIELD OF THE INVENTION

The present application generally relates to electronic cigarettes, and more particularly, to a heat not burn electronic cigarette device and a method for controlling temperature of the same.

BACKGROUND OF THE INVENTION

For all the heat not burn electronic cigarette devices shown in the market, most of them have the same type of software algorithm logic on their systems. Specifically, there is a built-in program written on the chip, which runs a pre-set data flow to control the heating features, to heat up the special cigarette and product vapor. Here, the special cigarettes are one-third of the size of traditional cigarettes. They are filled with compound tobacco rolls and are invented for heat not burn electronic cigarette devices only.

The abovementioned programs send one-way signals, outputting a changeless wattage on the heating component no matter what variation applies to the heating subject. It might work well on the special cigarettes since all of them have the same diameter, moisture and density. However, it would reach its limit if the heating objects are traditional combustion cigarettes. More specifically, there are hundreds of cigarette brands on global market. Each of them comes with slightly different size and filled with different species of tobacco leaf, which makes the heating process become uncertain for different individuals: some of them might be over-heated while some might be under-heated.

Therefore, there remains a need for a heat not burn electronic cigarette device and method thereof to allow the user to experience different cigarette via heat not burn devices.
